Ta allwhomit may concemr Be" it known that we; LnoN Sl- MOORHI JAD andMAURIGE G; Beam; citizens of the United States, residing, respectively.at Los Ange has. in thecbuntybf Los Angeles, State of C lifornia,and-Eureka, in the county of k Humboldt and Stateof California,haveinwhich may be operatedbyvehicle to indicate to approaching alsopedestrians; whether orvented a new'and usefulDirection-Indicator, ofwhich the following is 'a specification;

The primary object of this invention is to providea vehicle directionindicating device the driver oft-he h and following vehicles,

not a" right orleit turn is to'jbe made, and

,thednvention resides in the provision of a device'of this characterwhich'is simple in construction, reliable 1n operatlon and inex ensiveto manufacture. P

Another object'of this invention is to"pr0-' vide a novel form o f;indic'ating device which isoperated by'a motor controlled from the drivers"seat of the vehicle and rotates in Oppositedirections to indicatecontemplated movements of the vehicle, the device being so constructedthat the contemplatedinovement .7 electrical circuit throughout theseveral views,

Asuitable electrical motor 2 is mounted upon the bottom wall 3- of thecasing 1,- and has a shaft 4 which pro ects through the front wall ofthe casing 1. Fixed to the outer end of the shaft and spaced from thewan 5 of the casing is a circular indicatingmer'nber 6 in the form of adisk,

which is of slightly less diameter than the casing. It will be notedthat e rounded Specification of Letters Patent.
